A What is a "quantum potential" ?

  1. Mar 7, 2016 #1
    I am asking that question having in mind the following paper: http://www.sciencedirect.com/science/article/pii/S0370269314009381

    Now, reading Brian Koberlein blog, I saw his take on the model I've presented earlier.
    https://briankoberlein.com/2015/02/10/beginning/
    In there, he says: "The model predicts that the universe had no beginning. It existed forever as a kind of quantum potential before “collapsing” into the hot dense state we call the big bang."

    So I would like an explanation on what that means. Would I be wrong to say that the "quantum potential" can be conceptualized as a body of water and the "collapse" as that body of water freezing?

    To learn about quantum potential, google about "Bohmian mechanics".

    Unfortunately I had no luck. Perhaps someone could lend a hand?

    Greetings. I had some luck and someone provided me with an analogy so I'm curious what you think of it.

    Basically, in this paper the Universe is like a ping poll ball bouncing on water. Every time the ball bounces on water, it creates a ripple which changes the ball's trajectory when it hits the water again. In this paper, the "ball" has been bouncing infinitely into the past but at some point something caused it to stop bouncing and it "collapsed" into the hot dense state we call the "big-bang".
